The TS-24 is a larger-cell propagation tray built for plants that need more room to develop before they go in the ground. With a 292 cc cell volume and complex internal wall structure that delivers air-root pruning throughout, it's well suited to Australian natives, ornamentals, and any species where root quality and field survival matter.
How Air-Root Pruning Works
The TS-24's internal wall structure and side-slot openings guide developing roots toward air gaps as they grow outward. When a root tip reaches the gap, it desiccates and stops elongating naturally — triggering the plant to produce more lateral branching roots instead of a single spiralling mass. The result is a strong, vigorous root system with a higher proportion of young, active roots that establish quickly after transplant.
Holes between cells improve airflow around the root zone, reducing the humid, stagnant conditions that invite fungal disease. At extraction, the cell taper and side slots allow the plug to release cleanly without damaging the root ball.
What Makes It Different
- 292 cc cell volume — generous space for species that develop larger root systems before transplant
- Air pruning on all four sides — produces a denser, more vigorous root ball compared to standard smooth-walled cells
- Improved airflow between cells — reduces fungal disease risk in humid growing environments
- UV-stabilised virgin HDPE — designed for a service life of up to 20 years with correct handling
- Secure nesting for stable stacking — saves space in storage and on the bench

Frequently Asked Questions
What plants is the TS-24 best suited to?
The TS-24 suits any species that benefits from a larger cell volume and deeper root development before transplant — including Australian natives, ornamentals, revegetation species, and larger-format seedlings. If you're propagating plants that will go into challenging conditions or need to establish quickly, the extra cell depth makes a real difference.
How long will the TS-24 last?
With correct handling, TS-24 trays are built for a service life of up to 20 years. The UV-stabilised virgin HDPE construction resists degradation from sunlight and the general wear of regular nursery and garden use.
Why do holes between cells matter?
In a tray packed with developing seedlings, airflow around the root zone can become restricted — creating the warm, humid conditions that favour fungal disease. The inter-cell holes in the TS-24 keep air moving around each cell, reducing that risk without any extra effort on your part.
